32-18 CALCULUL COEFICIENTULUI DE CONTRACȚIE AL UNUI ORIFICIU ȘI REPREZENTAREA GRAFICĂ A REZULTATELOR CU PROGRAMUL SIGMA PLOT

THE CALCULUS OF THE CONTRACTION COEFFICIENT OF AN ORIFICE AND THE GRAPHYCAL RESULTS REPRESENTATION WITH SIGMA PLOT PROGRAMME

 

This paper presents the continuation of the studies from the last two articles presented at the last two Sebeș conferences. The authors used the same numerical method to integrate the Navier-Stokes equations and the presentation is done this time using a Sigma Plot programme. The study is performed with a combination of symmetric and asymmetric orifices at the same Reynolds number. The authors used again the method of finite differences to determine the flow through a tank and through the contracted section of the liquid passing an orifice.

 

Keywords: flow coefficient, current lines, symmetrical orifice, asymmetrical orifice, hydrodynamic spectrum, numerical methods

Cuvinte cheie: coeficient de debit, linii de curent, orificiu simetric, orificiu asimetric, spectru hidrodinamic, metode numerice
